In 2007, the Building Committee approved a redesign of Karmeliterplatz and the area surrounding the St. Christopher Memorial. Due to a lack of funding, the project could not be implemented at first. In 2011, thanks to a private donation, the memorial and the area surrounding the church ruins were upgraded; however, Karmeliterplatz and the adjacent paths remained unchanged. Starting in 2015, the project became part of the Integrated Downtown Development Concept (IEK) and received funding through the “Active City Centers” program. After funding ended in 2022, planning continued due to the significance of Karmeliterplatz and Brückenplatz as key connecting points and hubs for pedestrian and bicycle traffic. In early 2026, it was decided to reapply for the urban development funding program. The goal is to revitalize Karmeliterplatz and Brückenplatz, improve the quality of the public space and connectivity, and contribute to climate protection, biodiversity, accessibility, and the removal of impervious surfaces.

To gather ideas, a framework plan is currently being developed with citizen participation.

Specifically, the following steps are planned:

1. Development of the urban planning framework (framework plan);
2. Coordination and involvement of the relevant departments;
3. Public participation;
4. Political approval of the framework plan;
5. Preparation and subsequent implementation of the planning process.

Mainz Old Town

A draft master plan for the future development of the area is currently being prepared. It will be presented to the citizens of Mainz in the winter of 2026/2027. The City Council will then discuss and decide on the master plan. Once the decision is made, the planning process will begin.

The expected costs are currently being determined as part of the planning process and the eligibility assessment. If the project is included in a federal-state urban development funding program, up to 90% of the costs may be covered by grants.

A framework plan is currently being developed. This will serve as preparation for a planning process for the Karmeliterplatz and Brückenplatz areas, including the connection to Rheinstraße.
